[Morpho-functional characteristics of invagination esophago-enteric and esophago-gastric anastomoses]

The morphological and functional features of invagination ++esophago-enteric and esophagogastric anastomoses were studied in 234 of 266 patients who underwent gastrectomy or proximal resection of the stomach for cancer in 1972-1989. Two valuable stable properties were found to be characteristic in normally functioning invagination anastomosis: reliable anti-reflux properties and evacuation in portions. They are ensured by the obturating apparatus of the anastomosis, which consists of a valve and a muscular sphincter. No functional disorders on the part of the anastomosis were encountered in all periods after the operation in 174 (74.4%) patients. Complications developed in 60 (25.6%) patients (acute anastomositis, spasm of the anastomosis, reflux esophagitis, cicatricial stricture, and the dumping syndrome); they were attended by disorders of the function of the anastomosis due to temporary or constant disorders of the function of the obturating apparatus.
